PEGGlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 763,466, dated June 28, 1904,

Application filed July 16, 1900.

To all whom it may concern:

Be it known that I, JOHN F. DAVEY, of Beverly, county of Essex, and State of Massachusetts, have invented an Improvement in Pegging-Machines, of which the following descriptiomin connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to a peggingmachine, and is mainly embodied in an improved peg cutting or trimmingdevice and the operating mechanism therefor, the object being to obtain an effective trimmer operating close to the surface of the work-support and so arranged that the cutting portion is'entirely out of the path of movement of the awl in the feeding operation. In machines of this class the horn is commonly bent or offset, so as to enter the toe portion of the shoe, and is arranged to be rotated atthe will of the operator without interfering with the working of the machine as the shoe is pegged, sothat the operator can hold the shoe in such a manner that the horn will be close to the edge of the sole as the shoe is fed along. To have the pegs driven close to the edge of the sole, it is necessary that the support and connecting mechanism should be as small as possible, while in order to give an adequate support for the material it is desirable that only such space should be left in the support as is necessary for the feed movement of the awl, which projects below the support during such movement. .This is accomplished in accordance with the present invention. by providing the machine with a support the diameter of which is only slightly greater than the feed movement of the awl and causing the said awl to travel diametrically from one side to the other of said support in the operation of the machine. To

accomplish this, the cutting device itself is utilized as a portion of the support and includes not only a cutting member which in itself forms a partial support for the material, but a supplemental supporting portion, between which portions there is a channel extending diametrically across the support, the

Serial No. 23,756. No model.)

said cutting device and supplemental supporting portions being connected together and so arranged with relation to the remainder of the machine that the channel will always be parallel to the direction of feed movement of the aw-l regardless of the position of the horn except during the cutting operation, when a movement of the said cutting device and support is produced with relation to the awl and driver to trim the end of the previously-driven peg.

A further feature of the invention consists in so constructing the feed-channel through the cutting device that the walls thereof in the middle, where there is nocutting edge, project toward the path of the awl, with such space between them as to permit the free movement of the awl when straight, but to engage the same if bent and bend it back to its normal condition, so that it cannot possibly come in contact withthe cutting edge. Beyond the middle at each end the walls of the channel are separated to a greater extent and inclined toward the narrow portion, so that the awl, if bent, will engage the said inclined portion in the feed movement and be properly straightened.

While in some cases it is desirable that the cutting device should be oscillated in the horn to perform the cutting operations, it is of advantage to cause the said cutting device to make a complete rotation at each operation, cutting the peg and turning completely around until it reaches its original position, then stopping during the punching and peg-driving operations. By this construction the tendency of the material to be drawn away from the gage in the return movement of the cutting device is obviated, while the inner surface of the material against which the cutter bears is less likely to be damaged when the move ment always takes place in the same direction.

The invention further relates to novel operating mechanism for the cutter whereby such rotary movement is obtained, the mechanism being so arranged that the cutter at each operation makes a complete rotary movement without possibility of stopping short or overthrowing.

Figure 1 is a vertical section of the upper portion of the horn of a machine constructed in accordance with the invention, the top of the horn being shown in elevation. Fig. 2 is an enlarged plan View of the top of the horn; Fig. 3, a vertical section of the top of the horn on the same scale as Fig. 2'; Fig. 4E, adetail in perspective, showing the cover for the end of the horn; Figs. 5, 6, and 7, details showing in perspective the several parts of the cutting device; Fig. 8, a similar view showing a modification of the cutting-member; Fig. 9, avertical section of the lower portion of the horn and the mechanism for operating the cutting device; Fig. 10, a horizontal section taken'on a line near the bottom. of Fig. 9; Fig. 11, a detail mainly in elevation looking toward the right of Fig. 9; Figs. 12 and 13, details in perspective of parts of the cutter-actuating mechanism; Figs. 14 and 15, vertical and horizontal sections, respectively, showing a modification of the cutter-actuating device; Fig. 16, a general view, mainly in vertical section, of the lower part of the machine, the modified form of cutter-actuating device being shown for convenience; Fig. 17, a detail on an enlarged scale, showing the means for connecting the cutter-actuating mechanism with the operating-shaft of the machine; and Figs. 18 to 22, details of a modified cutting device especially adapted for use with the modified cutter-actuating mechanism shown in Figs. 14: to 16.

The invention relates to that type of machine in which the awl descends and completely penetrates the material, so as to project below the undersurface thereof, and then moves laterally to feed the material. After such lateral feed movement the awl rises and moves back, the peg then beingpresented and driven into the hole previously made by the awl. In this type of machine it is essential that there should be an opening in the work-support of sufficient size to permit the lateral feed movement of the awl, which after it has been forced through the material projects below the surface of said work-support. In order. to provide such an opening and at the same time to support the work close to the point of impact of the awl and peg, the cutting mechanism in accordance with the present invention is so arranged as to afford part of the work-support, said cutting mechanism having an elongated channel of sufficient width to permit the lateral movement of the awl and means for retaining the said channel in line with the feed movement of the awl except during the cutting operation if, as is commonly the case, a rotatable horn is employed. As

herein shown, the cutting device is provided with a cutting member (4, having a cutting edge a? near one end thereof, the said member being so shaped as to also afford a supporting-surface for the material. The said cutting member is mounted on a carrier 7), so arranged as to be capable of rotary movement in the upper end of the horn c, the said horn being shown as provided with an annular supporting-shoulder 0 surrounded by a flange c, which fits the carrier 6 when the latter is supported on the shoulder 0 The carrier 6 is provided with a central opening 6 the diameter of which is slightly greater than the extent of feed movement of the awl, which passes down through said opening in the punching operation and then travels diametrically across the same from one side to the other. Since the opening has to be of such size as to accommodate this feed movement, it is obvious that if the work were merely supported upon the surface of the carrier around the said opening it would tend to bulge inward in the punching and driving operations. To afford an adequate support for the work, therefore, a portion of the cutting member a is utilized, and in conjunction therewith a supplemental supporting member a is also em ployed, the said supplemental supporting member being also mounted in the carrier 1). As herein shown. the said cutting member and supporting member are arranged to fit, respectively, in recesses b and 5*, formed along the upper surface of the member 6, the said parts being held in position by means of a top or cover (Z, which is adapted to be secured to the end of the horn, and is provided with an annular supporting surface overlying the parts a, a and b and also fitting over the flange 0 so as to maintain all of the said parts in place. The said cover is shown in perspective in Fig. 4 and has a shank d adapted to be fitted on and secured to the horn. The surfaces of the parts (a and a project upward from the bodies thereof, the thickness of the upwardly-projecting portions being substantially equal to the thickness of the annular portion of the cover (Z, so that the said cover and the said parts together afford a substantially flat support for the material, as best shown in Fig. 3. The horn is offset at its upper end in order that it may be inserted in the shoe to be pegged, and to properly present the said shoe in all the necessary positions the horn is'rotatable, being mounted on a shank o rotatably supported in a horn-supporting sleeve 0 at the front of the machine.

To trim the pegs, it is necessary that the cutting edge of the member a should travel across the line of driving, and it is also essential that in the normal position of the said member a and its cooperating supporting member a they should be so related to the horn that the channel between them will be along the line of feed movement regardless of the position of said horn. To accomplish the cutting and also to insure the proper location of the cutting device, as stated, the said parts IIS are arranged to be rotated or oscillated in the 3 tation at each cutting operation.

cutting operation and alsotobe prevented from rotation with relation to the awl and driver except when such rotation is required for the cutting operation. For this purpose the cutting device is arranged to be operated by means of a rotating or oscillating rod-e, extending upward through the horn and provided at its end with gear-teeth c intermeshing with gear-teeth 72 formed on the under surface of the member 5, Fig. 7. The said rod 0 is connected by bevel-gears 6 with a supplemental rod 6 whereby the said rod may be operated properly above ,the bend in the horn, and the rod 6* is provided at its lower end with the gear 0 connected through an intermediate gear a with a gear 6. upon an operating-rod a which projects upward through the shank 0*of the horn. The gears 6 e and c are located in an offset portion of the horn, which .is so proportioned that the supporting .end of the horn is directly above the axis of rotation thereof, as is necessary :in order that the mate-rial maybe properly presented to the peg-driving mechanism'in the operation of the machine. These gears serve to maintain the proper position of thecutting device relative to the awl and peg driving mechanism, it being obvious that if therod e and its gear 6 are stationary during the rotation of the born the said rotation will produce, through said gears, a corresponding rotation of the cutting device with relation to the horn, which will keep the said cutting device always in the same position relative to the awl and peg driving mechanism in the top of the machine. In the same way if the rod 6 is rotated or oscillated it will produce a corresponding rotation or oscillation of the cutting device from its normal position thus maintained, andthereby.

cut or trim the endof the peg which has been driven.

As best shown in Figs. 9 to 11, inclusive, the rod 0 is arranged to have a complete ro- The rotary movement is imparted to the said rod by means of an elbow-lever f pivoted at f and connected at one end with a reciprocating rod f, the other end of said elbow-lever being provid ed with a segmental gear f, which, through intermediate gears, as will be described, connects with the rod 6 The rodf is reciprocated by means of a cam f Fig. 17, on the main shaft of the machine, the said cam having a curved channel f to receive a projection f connected with the rod f: The said segmental gear f is beveled and arranged to intermesh with asimilar gear g upon an oscillatingmemher 9, which has a bearing concentric with a gear h, which is arranged, as will be described, to be moved a certain distance in one direction in response to the forward or operating movement of the oscillating member g and to be held stationary during the inoperative movement of said oscillating member. The parts are so arranged that each operative ducing-gear (shown as the connected gearwheels i and 2' with a gear 6 upon said rod 6 In order that the horn may be depressed, as is common in this type ofmachine, the gear 6 is, provided with elongated teeth, so that it can slide up and down with relation to the gear 2' without getting out of mesh. therewith.

The horn-depressing mechanism, adjusting devices, &c., which are incidentally shown in the drawings, need not be particularly described herein, since they form no part of the present invention.

- In order to keep the cutting device always properly positioned with relation to the work,

it is essential that the said device when completely rotated should make at each operation onecomplete rotation without fail, it being absolutely essential that the said device should neither overthrow nor fall short. To this end .the gear his provided with a locking detoward a suitable ratchet-surface if, connected with or formed on the gear it. This ratchetsurface isshown in Figs. 12 and 13 as formed on a separate ring secured, as by'screws it, to theface of the gear h. The arm 9, which ,carries the pawl or plunger g overlies the face ofthe gear, and the said plunger is spring-pressed downward by means of a spring g, so thatin the rearward movement of the arm g the said plunger will ride up'the inclined side of, one ratchet-tooth and drop behind the perpendicular. side thereof, so that lock the gear, the movement of the member 9 is slightly greater than the feed movement of the gear it, so that when the said member g moves back to its starting-point it will carry the plunger 9 beyond the engaging surface of the next ratchet-t0oth,so that it is capable of a in the next forward or operative movement slight forward movement before engaging said ratchet-tooth at the next operation. During such forward movement it is adapted to unlock the locking device b, so as to leave the gear it free to travel forward. For this purpose the said member g is provided with an engaging member ghhaving an inclined surface g ,adapt ed to engage a portion of the locking device in such a manner as to disengage the projection I? from the notch it. As herein shown, the inclined surface g engages a corresponding inclined surface m, formed on a rocker m pivoted at m and so connected with the locking device I; that the pivotal movement will move said device is on its pivot until the projection 73 passes out of the notch it. As herein shown, the member 172 has an elongated slot mi into which projects a pin 75 from the locking member 71:, so that the movement of the member m will cause a corresponding movement of the member 7:; to unlock the gear h. The member m and the member 7. are shown as pivoted in a support A mounted on the frame A below the gear 71., and both are normally held in the position shown in Fig. 11 by means of a spring on, which acts directly upon the member m In order to permit the rearward movement of the member 9 without unlockingthe gear, the said member is shown as pivoted at 9 upon the arm 9* and provided with a stop g which locks it when in its operative position, and a spring g, which permits it to rock upon its pivot when engaged by the member in as the said member g moves to the rear. The inclined surface g of the said member in such rearward movement engages a portion of the member m riding over the same and yielding without prod ucing any movement of said member m In the position shown in Fig. 12 the parts are about to operate, and it will be seen that as the member g moves forward. the member will engage and move the member m so as to throw the projection out of the notch it before the pawl g engages the ratchet-shoulder to produce the movement of the gear 72. At the end of the movement of the member g the gear it will be engaged by the locking device, which drops into the next succeeding notch, thus stopping and locking the gear in the proper position. It is thus rendered impossible for the gear it to overthrow, since the locking device positively determines the successive positions of said gear, so that by the end of each operation the cutting device is left in the proper position to admit of the next pegging operation.

WVhile the complete rotation of the cutting device is in many cases desirable for reasons hereinbefore stated, this operation isin some types of machine impracticablefor example, in machines in which the awl and driver descend at the same time, so that the peg has to be trimmed while the awl is projecting through the material. In a machine of this class it is practicable to oscillate the cutting device, causing the same to move farenough in one direction to sever the peg and then to return in the opposite direction to its normal position prior to the feed movement. As shown in Figs. 14 and 15 and incidentally in Fig. 16, the elbow-lever f is connected by a universal joint with another elbow-lever n, which is shown as having'a vertical pivotal axis at n andwhich is provided at one end with a segmental gear n which meshes directly with the gear 6" upon the rod a The vertical reciprocating movement of the rod f will produce an oscillating movement of the-elbow-lever and a corresponding oscillation of the rod 0 so that the cutting edge will travel back and forth across the driving-line tosever the projecting end, of the peg.

As shown in Figs. 18, 19, 20, 21, and 22, the shape of the cutting device as a whole is somewhat modified in this construction, it being necessary to make the supplemental supporting part of the cutting device smaller, so that it will not come in contactwith the awl during the oscillating movement of the cutting device as a whole. While therefore a larger space has to be afforded in the support to ac-" commodate the several movements of the working parts than in the type of machine where the rotary cutting device may be employed, it is still practicable to support the work with a much smaller tip or support than has been heretofore employed, so that in either type of machine a material advantage is gained by the arrangement which embodies the present invention. Furthermore, the cutting edge of the cutting device is protected from injury by accidental Contact with the awl, since the walls of the channel through which the awl must pass in the feed movement act as guides or deflectors to straighten the awl if bent, so that it cannot come in contact with the cutting edge either prior to or during the cutting operation.

As shown in Figs. 8 and 20, a saw-tooth edge a may be substituted for the knifeedge, the movement of the cutting device and shape of the cutting portion being such that the saw-teeth will operate to advantage.
